Embodiment 1

[0045] Please also refer to Figure 1 to Figure 3 , the contact type super-slip encoder provided by the present invention is now described. The contact type super-slip encoder includes a code disc assembly 1, a reading assembly 2 and a housing 3, the code disc assembly 1 is connected to an external fixed part, the reading assembly 2 is connected to an external rotating shaft 7, and the housing The body 3 is covered on the outside of the code wheel assembly 1 and the reading assembly 2, and the entire encoder is protected by the casing 3, and the casing 3 will not rub against the code wheel assembly 1 and the reading assembly 2 .

[0046] The housing 3 is fixedly connected to the code wheel assembly 1, a buffer layer 4 is placed between the housing 3 and the code wheel assembly 1, and one side of the buffer layer 4 is fixedly connected to the housing 3 , the other side is fixedly connected with the code wheel assembly 1; the buffer layer 4 can support the code wheel assembly ...

Embodiment approach

[0061] Further, see Figure 6 , as a specific embodiment of the contact type super-slip encoder provided by the present invention, the contact part 22 also includes a fixed head 221 and an elastic member 222, and the fixed head 221 connects with the rotating disk through the elastic member 222 21 is fixedly connected, the fixed head 221 has an arc-shaped surface towards the side of the super-slip code wheel 11, and the super-sliding piece 223 is fixed on the side of the arc-shaped surface closest to the super-slip code wheel 11, that is The super-sliding sheet 223 is located at the bottom of the entire fixed head 221, and the bottom of the fixed head 221 can only fix one super-sliding sheet 223, and can also fix a super-sliding sheet group, that is, a plurality of super-sliding sheets 223 are assembled to form The larger size Ultra Slider set.

[0062] Both sides of the super sliding sheet 223 are arc-shaped surfaces. At this time, when the entire super-sliding code disc 11 i...

Embodiment 2

[0071] refer to Figure 4 and Figure 5 , as another specific implementation of the contact-type super-slip encoder provided by the present invention, the difference between this embodiment and Embodiment 1 is that the housing 3 is fixedly connected to the reading assembly 2, and the housing 3 and the reading assembly 2 are provided with a buffer layer 4, one side of the buffer layer 4 is fixedly connected to the housing 3, and the other side is fixedly connected to the reading assembly 2; the buffer layer 4 can be used for reading Component 2 is used for support, and the contact and fit between code wheel component 1 and reading component 2 makes the positions of code wheel component 1 and reading component 2 inside the housing 3 relatively fixed, preventing code wheel component 1 from being separated when bumping .

[0072] The two side surfaces of described super slippery code wheel 11 all have described coding code track 111, and the quantity of described rotating disc 2...

Abstract

The invention provides a contact type super-slip encoder, including a code disc assembly and a reading assembly, the code disc assembly includes a super-slip code disc, the super-slip code disc has at least one code track, and the code track has an atomic level flat surface The reading assembly includes at least one rotating disk, the rotating disk is opposite to the super-slip code disk, the rotating disk is provided with at least one contact part, the contact part slides along the coding code track, the contact part includes at least one super-sliding piece, the super-sliding piece Super-slippery contact with atomic level flat surface and output coded signal. The contact type super-slip encoder provided by the present invention can directly output a certain code system through the design of the super-slip code disc, and the size of the super-slip sheet is generally small, so it can be installed inside a small-scale super-slip code disc. More layers of encoding code channels to achieve higher precision and high resolution encoders.

Description

technical field [0001] The invention belongs to the technical field of encoders, and more specifically relates to a contact type super-slip encoder. Background technique [0002] A rotation angle measuring device (also known as an encoder) is a device that measures angle and rotation speed, which can be used in many fields, such as for measuring motor speed or angle control, etc. According to different contact methods, encoders can be divided into contact encoders and non-contact encoders. Non-contact encoders can be divided into optical encoders, magnetic encoders, or capacitive encoders according to their working principles. However, many of the above This kind of non-contact encoder has low precision, and is susceptible to various problems such as electromagnetic interference or strong light interference, and has poor reliability. [0003] The contact encoder is composed of a code disc and a brush. The brush is a movable contact structure. The code disc is rotated under ...
